First of all, listing means that the federal government is required to take conservation measures to prevent harm, and support recovery. Without listing, there are few regulatory mechanisms to compel the government to pro-actively protect and restore particular species. It is especially important to have this tool for species conservation when the species is controversial, obscure, or underappreciated, or when protecting the species could inconvenience someone or cost money. The law provides a means of protecting those (in this case, imperiled species) that would otherwise have no "voice" in our political and legal system.
Blah, Blah, Blah......No Treatment, No Cure means no way of protecting them. I think the real point of this is to give the federal government a longer reach to (as Todd says) bully and strong arm private landowners to close access to their caves.
Second, this accountability means that the government must show what it is doing to protect the species, and in order to take action, usually some amount of resources must be devoted to the effort. Listing usually brings funding for conservation measures. In the case of the little brown bat, one of the most pressing needs is research on white-nose syndrome, and to date, this has been inadequately funded, at best.
Everyone is already doing everything they can and there is already unprecedented amounts of money being dumped into this crisis. Where is this "magical" money going to come from? Perhaps if they (CBD) would stop filing lawsuits, FWS could devote more resources (money) into the real crisis instead of having answering their stupid petitions.
Third, critical habitat for the species is usually designated. Species need places to forage, reproduce, and carry out other vital aspects of their life cycle. In the case of the little brown bat and other bat species affected by white-nose syndrome, they need safe places to hibernate. Designation of critical habitat for the little brown bat would protect crucial sites for its survival and recovery. As the attached paper describes, critical habitat is a great aid to species' recovery.
And just where and how do they think this will be accomplished? LBB bats are not as particular about their habitat as greys or Indiana's and they often hibernate solitarily. At least that is what I have witnessed. Maybe someone can correct me here and expand on this?
Fourth, listing of a species is often followed by the development of a recovery plan. This is a "map" for how the species will be protected and nurtured back to a stable, healthy population level. The attached paper also addresses how species with recovery plans fare better than those without.
FWS already has a plan for managing WNS, how will a separate plan devoted to LBB help?
